the comfort level from this mattress is a whole new level, I have been using this mattress for over a month now. I have had very noticeable difference, and I had no idea how much impact a mattress can have on our body. I have full night rest, I use to toss and turn so much I would wake up I thought that was due to fatigue but that is so rare now I hadn't noticed it had almost stopped, I also would wake up with cramps and i am so relieved to say that's stopped also. this mattress is so comfortable, and its combination of coil density system and Gel memory make it the best mattress i have ever slept on. I do not feel like i fall in like some gel memory beds but i feel like it shapes to my body while giving me the perfect amount of support. I highly recommend this Serta Prefect Sleeper Pillow top Mattress for its quality and help it has personally given me. a 10/10
